Hi

I have been running and continue to run the latest linux mint on my NUC6i7KYK without any real problems (though it would be nice if it played nice with my 4K monitor using max resolutions - but I can live with 1920x1200).

Recently I tried to boot off a windows USB to do something I needed windows for, only to find I could not select F10 (or F2/F7)- even though it gives me the menu for them on a cold start (never on a restart). I tried everything from different cables to different keyboards (including wired) to no avail.

Eventually I tried to update to the latest BIOS (50) using the methods on your site that don't require F2/F7/F10. None worked. For example, with the remove BIOS jumper, BIOS on usb, then turn on method it just got caught up in a loop turning on and off again every 10 or 15 seconds ???

I would appreciate any ideas - including anything I could try from inside my working linux mint.

I would love to buy a NUC7i5 but can’t find a list of
multiple USB-C (Display port) to HDMI Cable to select from, I do understand I
can only need and use ONE.  I also see
many post on https://communities.intel.com
about usb-c to HDMI cables that don’t work.
Not going to buy one until I can confirm a cable to buy.  Also, this ONE ISSUE has me researching other
NUC like computer that hopefully have 2 video ports like any combination of
HDMI and DisplayPort.  Also, kind of HATE
the idea of tying up my One Thunderbolt 3 port for an HDMI Cable would have preferred
to give up an USB 3 port for DisplayPort.
I also find the information about this on https://www.intel.com/content/www/us/en/support/articles/000005571/mini-pcs.html
completely inaccurate because it implies you can connect two monitors with
PURELY HDMI Cables and yet the NUC7i5 only have one.  And the link to the  Multiple Display Configuration Wizard completely
has no info on any of the NUC7’s

OR like a number of laptops I have seen have 2 USB-C / Thunderbolt Ports

As I have noted elsewhere in these forums I have been running a NUC7i5BNH with bios v46 and HD Graphics Driver v4678 for some time. I have also asked that Intel not concentrate on issues relating to 4k graphics resolutions to the exclusion of interests of people who wish to continue with bios v46 and HD Graphics Driver v4678. I have found that this combination of bios and graphics driver is the only one, so far, that gives me trouble-free video and HDMI audio at 1920x1080 resolution. All of the more recent drivers give me audio problems, and it could well be related to my requirement to persist with bios v46.

Yet HD Graphics Driver v4678 has now been removed from the search downloads for NUC7i5BNH. I see that this version is still being referred to in other forum threads, for example Audio issues at 4k on NUC7I5BNH . I would appreciate it if this most useful driver for anyone still running bios v46 could be restored to the search downloads list for this NUC.

Regards.

In a nutshell, the only issue I have with the NUC system is, the CPU fan would left turned on after ESXi shutdown while the NUC power button would be turned off. To turn the system back on with the power button, I would need to first pressing the power button for 5 seconds or so until the fan is turned off (the system is then forcefully powered off), only then I can turn the system back on again by pressing the power button normally. This annoys me as if I forgot to force the units to go down completely, I'd find the units are warm in the next morning and I don't have air conditioning running all the time. I had done a bit of research and did try a few things and unfortunately I had not found a solution to this, yet. I have two NUC units with the same parts and EXSi, both have the same experience.

Would appreciate your advise on what I should try.

And as much as I'd like to get some support regarding the above subject, I'd like share on this thread my experience of running ESXi 6.5 on the NUC units.

Hardware and firmware

Important hardware and firmware remarks

• For those planning to run ESXi 6.5 or similar, and for those planning to run Linux operating system on the NUC with Intel SSD 600P, I highly recommend that the SSD is updated with firmware version 121C (or better if available)
• There were issues reported running Linux on the Intel SSD 600P, at the time I'm writing this only Microsoft Windows versions listed on the 600P product page are 'officially' supported
• Having said, I had see reports on this forum and others that firmware version 121C works good for certain Linux flavors, and for me, ESXi - see also important notes on the NVMe driver for ESXi

BIOS configuration - configured according to article here by William Lam and article here by Erik Bussink - in summary, I have the following BIOS settings. I'm listing them for reference, not that I know what each of the settings meant

VMware ESXi

• Installed on the USB boot drive
• Updated to ESXi 6.5.0 Update 01 Build 5969303 here
• Two data store on each NUC, each data store fully occupy each 600P

Very important remarks

• Replace the stock NVMe driver that came with ESXi with the one built specifically for Intel SSD here
  • After the update, it showed intel-nvme instead of nvme as the driver for the storage adapter
  • You'll see on the driver page that the model 600P isn't listed, but the driver worked well for me so far
• I did the driver update after I had applied the ESXi 6.5.0 Update 01
• And prior to that, I had both of the 600P low-level formatted with HDAT2 (by verify/write/verify), the tool is listed here here

The catch was, without the intel-nvme adapter driver, I had painful experience working on the ESXi platform with the NUC system - obviously the system or its parts are not ESXi HCL listed

• Copying virtual machine folders from one ESXi data store to another ESXi data store that was created on another 600P on the same NUC would usually fail before 20% completion
  • ESXi would lose connectivity to the data store that it was writing after the error
  • I had to reboot to recover from the situation
• Or, similarly, copying virtual machine folders to/from the same data store would also result in similar experience
• Or, deploying virtual machines with thick disk mode (-diskmode eagerZeroedThick) with the VMware ovftool would also result in similar experience
  • Having said that, I didn't get any issue deploying virtual machines with thin disk mode

Post updating ESXi with the intel-nvme driver, I had tested the system to PASS the above test cases which failed 100% previously

Edits: there are 3 items attached to each NUC units

• The DC power plug
• The USB boot drive
• Cat5e network cable

No other items are connected other than the items above. Specifically I don't have any type of displays attached to the units.

Recently bought the Skull Canyon Nuc and went through the Windows 10 install /drivers/bios/firmware updates...

After the whole process discovered that after "shut-down" the fan will turn on itself very very high and persists,

but on a restart and the NUC is powered on the fan spins low and quiet, only on high loads do the fan kick in a bit but never full blown like when its shut down.

I tried windows 10 recovery/ another clean windows 10 install/update BIOS again/ re-installation of every single drivers but to no avail trying to figure out the problem.

Until once I unplugged the HDMI cable while the NUC was shut-down the fan stops! Must be a bad update on the HDMI 2.0 Firmware???

~ I messed up updating the HDMI 2.0 firmware on a non Device (Dell U2414H) and crashed, and only after did I do a proper HDMI 2.0 update on a compatible device, thinking it'll be fine.

Firmware updated with a 2.0 HDMI connected device (Samsung 6 series 4K TV), while remaining plugged to the TV the NUC shuts down perfectly with no fan activation.

But once booting in or shutting down while connected to a non HDMI 2.0 Device (Dell U2414H) the fan issue starts again and will become persistent until another update of the 2.0 firmware is done.

HELP!! how do I fix this and is the HDMI firmware issue or do I actually have a faulty unit.

I'm having an issue where the NUC6I7 puts the monitor to sleep, but if it sits like that long enough the monitor never comes back.

I have to shut the system off.  Unplug the power, and the monitor, and the power from the monitor, then turn it all back on.

Latest BIOS, Display Drivers, etc.

When connected through HDMI ports on NUC and Monitor ( both HDMI 2.0's), when the Monitor goes to sleep it can not be reawaken and the speakers start chirping as if you just connected some other device and they do not stop.

The only way to wake the monitor is to switch to another input and revert back to the original HDMI1 or HDMI2 on the monitor.

On the Display ports it seems to work fine.

All Drivers are up to date !!!!

Configuration is

NUC6i7kyk

  32Gb of RAM

  M.2 - 512 Gb - SSD 960 Pro

Latest Drivers are:

  BIOS  Version 050

  Iris Pro 580 - Driver version (Win 10-64 - 15.46.05.4771 KY  download)  22.20.16.4771

  LG - LG ultra HD (HDMI)

  HDMI 2.0 Firmware  version 0x07 0x20

  Realtek High Definition Audio - Ver 6.0.1.7982

Is anyone out there having a similar problem.  Or is there any suggestions on how to fix this annoying problem.

Thank you

mein nuc skull fan ist defekt ! wo kann ich es kaufen ! vielen dank !

I am having issues with my NUC7i7BNH where the screen most of the times is not coming back out of sleep mode (sometimes it does work as how it should be).

The keyboard seems still to be responsive (numlock light is still going on and off), but the monitor does not come back. I installed the latest version (4678) of the Intel Graphic drivers and all other drivers are the latest as well.

I am running Windows 10 Pro version 1703. I have seen that there are quite some users of the NUC7i7BNH that reports on crashes of their NUC. Maybe mine issue is the same, but I don't know. The only thing I can think of is long pressing the power button to restart the NUC, but I think the NUC is not crashed, but I can't tell for sure as the screen remains blank.

One other thing that I find particular is that the Intel Driver Update Utility (V2.8.0.7) shows an unknown version number for the following two drivers:

- Thunderbolt Bus Driver for Intel NUC Kit NUC7i5BN and NUC7i7BN

- Intel HD Graphics Driver for Windows 10 for Intel NUC7i3BN, NUC7i5BN and NUC7i7BN

Hope someone can inform me what I can do to resolve the issue that my screen does not come back when in sleep.

I got my nuc about 1.5 months ago, about a week ago I updated bios/graphics driver and ever since have been experiencing issues. The NUC seems to lock up whenever the display is disconnected. Either by windows putting it to sleep, or even if I unplug the hdmi cable. Primary display is a 2017 Vizo E-60-e3, but I have confirmed it on a 1080p pc monitor as well. I tried rollling back the drivers, but it wont boot with anything but the most recent drivers and the stock windows drivers. The issue does not happen on the windows drivers. Thanks in advance for assistance!

I have all the latest bios/drivers installed and noticed my network speed fails to initialize a 1000Mbps connection and uses a fallback to 100Mbps.

(Network driver is version 22.7.1)

I have the nuc connected to a gigabit switch which shows the connection speed with its leds ... orange being 100Mbps, green 1000Mbps

When the nuc boots, I see the network come up 3 or 4 times for 1 or 2 seconds in gigabit mode always losing connection (all lights out), then eventually it stays active in 100Mbps mode.

When I go to the properties of the network adapter, I see in the link speed tab, (its set to auto negotiation) current speed is: "100Mbps Full Duplex (EEE: Not Negotiated))"

I know gigabit was working before, unfortunately I cannot say what version of the driver was working and when it stopped ...

I have an Intel NUC NUC5i3RYH that is having a peculiar problem. Here are the details.

Setup:

1. Intel NUC NUC5i3RYH

2. One Internal Seagate 1 TB Hard Drive - OS is installed on this.

3. 16 GB RAM - 8 x 2 GB SO-DIMM's - Crucial

4. Two External USB 3.0 WD 2.0 TB drives connected to Rear USB Ports. Both are data drives, no boot partitions on these. These are both WD's but two different models.

5. USB Mouse and Keyboard - Connected to front USB Ports

Symptoms: The system is working fine except when cold rebooted. After a cold reboot the NUC goes into an indefinite boot loop. I just see the NUC Logo and then it reboots after a few seconds. Cannot enter the BIOS since the F2, F7 etc message does not appear on the bottom right of the monitor. The keyboard and mouse are unresponsive.

Procedure to boot: Unplug both the external hard drives and reboot. The system proceeds to boot normally. Once booted, I can then plug in the two external drives and they appear to work fine. A warm reboot causes no problem and the system works properly and boots up just fine.

Things tried to resolve the issue: Tweaked all the BIOS settings like, UEFI Boot -> disable/enable, Watchdog -> disable/enable, USB xhci mode -> disable/enable and many other parameters as discussed throughout the forum. However the problem remains. I am running the latest BIOS as well. Version RYDBWi35.86A dated 1/18/2017.

Other Observations: Have tried powering up the external USB drives with a powered USB hub which has no effect, the system still goes into a boot loop. Also noticed that when the drives are attached the keyboard and mouse become unresponsive. It seems as the whole USB bus is hung till I remove the external USB drives. If I remove "both" the drives during the boot loop, I immediately get a message on screen saying that POST has failed and I could either press F2 to go into BIOS or F9 to continue. The keyboard and mouse come alive at this stage and I can press F2 to go into BIOS and start twiddling my thumbs . Last point, I did install this system using a 16GB Pen drive so apparently pen drives may be working after a cold reboot. I think the issue is with the two external drives plugged in.

Would appreciate if Intel support can look into this matter and provide a resolution. Would be happy to provide any more details as required.

Dear all, I am grateful for your help in advance.

I thought buying a NUC just 4 months ago, Win10, keeping the SSD in-brand with a 128gb SSD would be fool-proof for my ageing father system.

The system was working flawlessly, until he reports to me the error: PXE-E61 Media test failure, check cable.

He said it fixed itself once, and then since then continuing failure now.

I go into the bios and with UEFI Boot, there is no 'boot drive'.

But when I look in the chipset SATA controller: I can see M.2 NVME SSD: "Intel SSDPEK...." drive listed.

I pulled out the ram and m2 card and re-fitted it. still same error.

I presume this is either the M2.SSD or the NUC?

Im guessing it could be a problem with the NUC, as the M2 is recognised in SATA controller, but not able to locate a boot drive.

Im trying to work out what to return / RMA.

Many thanks for your help

TRIED ALL YOUR MINI PC's

you're probably have problem in the Real Time Clock (RTC) AND IT'S NOT CMOS BATTERY PROBLEM

the real time clock just resets back to default time and date (December/2016 00:00)

i have more than 30 pcs of Intel NUC5CPYH updated to Bios version 0064 All of them are new.

bought at different dates

The reason is that i'm the only one who complains about that problem is because of i'm using this nucs in offline-mode and it's impossible to connect them to the internet for time synchronization always

i checked voltage of cmos battery - it's correct (3v) and you all agree with me that it can't be that more than 30 pcs has the same problem

1. THE TIME AND DATE ARE STOPPING FROM MOVING

2. SOME OF THEM ARE REVERTING BACK DECEMBER 2016 00:00

3. IN SOME OF THEM THE TIME AND DATE STOOPING/REVERTED TO DEFAULT WHEN THEY ARE PLUGGED OUT OF POWER FOR 3-4 DAYS OR SO...

I have big organization of my customers that i sold the nuc for them, and now they want to fill a lawsuit against me because of that! it's absolutely not a operating system related issue because i see the time and date stop / revert problem as soon as i hit F2 to the bios , before the operating system boots up and i tried also to remove the hdd and see if it happens to nucs that stays offline without hdd - it happens!

tried every scenario you could imagine , including replacing the cmos battery although it's new nucs units (3 weeks-2 months since opening the box maximum)

IT'S ABSOLUTELY a BIOS BUG that you never could test at your development because i guess you and most of your customers using them with an internet connected and time sync ability.

please solve this issue for me , i'm bagging you i'm here any time to do any test that you want online with you 24 else i will get into big trouble with my customers and lose big money. 

NO CMOS ERROR / CMOS LOW BATTERY OR ANY ERROR MESSAGE IS LOGGED OR SHOWN DURING BOOT

Just for your notation According to this page CMOS Battery on the Intel® NUC

You tell customers that the CMOS battery do responsible for keeping the time running during power off for 3 years.

I'm sure this bug is not battery related issue after what i've tried

to test you must use a unit without any connection to the internet for time and date syncing                                                                                      

Bonjour! Mon mini-pc Intel-Nuc NUCPYH ne démarre pas et l'écran reste noir.

La solution pour qu'il démarre c'est qu'il faut  débrancher mon cable HDMI de la tv et de démarrer le mini-pc  apres  quelques seconde la lumiere arrire rouge Optical s'allume et je rebramche mon cable HDMI a la tv et tout est reparti.

Pourquoi et comment réparer ce probleme?

Hi,

My NUC7i5BNH has been generating some annoying high frequency noise since day 1. It's quite audible even when it's about ~3000RPM according to the BIOS set up. I have many laptops such as Thinkpad X1, and when idle I don't hear any noises for those devices at all. Is that expected or did I get a defective unit?

Also, whenever I briefly place the unit upside down, the noise is much higher and it sounds like something is getting scratched. Is it also expected? I avoid leaving it upside down and not sure if it's an indicator of the item being faulty.

Thanks!

Hi Intel Forum,

I have just installed a NUC6CAY(H) and receive an error message when booting up "CMOS time not set. Does this mean I need to replace the battery or do I need to reset the time. Please help with both if applicable.

Best regards,

Hello,

I'm hoping that someone can help.

I bought a NUC6i5SYH last November as a ready to run computer, with SSD, HDD, RAM, and windows 10 pro installed.

the computer has been working perfectly (apart from the loud fan) until around a month ago when I removed the HDD.

I started the computer once without the HDD installed, after I re-installed the HDD the BIOS doesn't recognise the SDD anymore (not populated) only the HDD and therefore the computer can't BOOT.

I contacted the seller who informed me that I had invalidated the warranty as I'd opened the computer but they would repair at a cost.

I let the IT team in my company look at the NUC but they couldn't fix the problem either even after installing the latest BIOS and think it could be a hardware problem.

After reading the threads here I'm not so sure it's hardware related as there seems to be a lot of problems with the BIOS and the SDD.

I have tried everything I can think of and also a lot of the suggestions in the other threads here :- checked that SATA SMART is ticked, PCI devices M2 is ticked, BOOT is set to RAID, disconnected the CMOS battery for a few minutes. I also tried to BOOT with internal UEFI shell ticked in the BOOT configuration. Nothing works, I would be very grateful if someone could help, as I don’t want to scrap the computer.
